There's only one such line. In general it's a good idea to reset the transform before clearing as the (0, 0, w, h) rectangle may not cover the whole canvas anymore. In this toy example there obviously isn't another transform so it's without function.

In the same vein, I've been using Zwibbler ( http://zwibbler.com/demo/ ) for all the illustrations on my blog ( http://vjeux.com ) and it's been really nice to have images that look like they have been hand drawn.

I believe the $2999 price is for licensing Zwibbler so you can have it on your own site/app. For example if you had a company that made custom t-shirts, users could create their own designs using Zwibbler on your site.

On the other hand, if you just want to draw some pictures using the Zwibbler demo to put them on your blog, you don't need a license, and it doesn't cost you anything.

This has made me so much happy. Thank you. Brilliant stuff. I've been looking for something that does this and have just started having fun with this problem using P5.js and playing around with splines, perlin noise etc.

Not joking at all, I assure you! Primary use case is for education/training materials where a flat or prescribed style is not desirable, and also because despite my girlfriend being an artist I have no ability there whatsoever and this has just removed a whole bunch of fear about presenting polygons.

I’m assuming the parent commentator wants handdrawn-like graphics for a service or machine generated content, but wants them in different styles. Thus, tweaking what you’ve written allows him to solve both.

That’s great, I’ve been looking for a Sketch 3 plugin that was doing that for a while (it doesn’t exist yet)
It could potentially be wrapped in a plugin.

When presenting designs, in some situations you may want to show rough sketches and not high fidelity (or people focus on details rather than the big picture). Something like that would allow me to easily toggle between high fidelity to rough state.
